What is y, when x = 7. y = 3x + 10
PLEAS HELP I NEED IT RN
Answer: y = 31
Step-by-step explanation:
y = 3x + 10
y = 3(7) + 10 Plug in the 7 for x, because it shows x = 7 in the question.
y = 21 + 10
y = 31

Find the value of x that will make a||b
The location of each angle make them vertical angles. For the lines to be parallel the two angles need to be equal to each other.
5x + 20 = 3x + 60
Subtract 3x from both sides:
2x + 20 = 60
Subtract 20 from both sides:
2x = 40
Divide both sides by 2:
X = 20
Find two integers whose sum is -5 and product is -14
Answer:
-7 and 2
Step-by-step explanation:
I hope this helps :)
Let me know if you need a full explanation
Answer:
Step-by-step explanation:
a+b=-5
a=-5-b, we are also given
ab=-14, using a found above makes this become
(-5-b)b=-14
-5b-b^2=-14
b^2+5b-14=0
(b+7)(b-2)=0
So the numbers are -7 and 2.

A store advertises 15% off an item that regularly sells for $300. what is the sale item? how is a 15% discount similar to a 15% decrease? Explain.
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).
Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.

find the perimeter using Pythagorean theory
Answer:
Perimeter: 32
X = 5
Step-by-step explanation:
If you draw a line to make the triangle the longer leg is equal to 4 then the shorter leg is 3 since your subtracting 13 - 10 to get 3 for the shorter leg. you use Pythagorean theorem that would equal 3^2 + 4^2 = 25 if you take the square root of 25 its 5. So now you know x = 5. Then add all the sides together to get the perimeter.
Three cards are selected one after the other from a standard deck of 52 cards.
What is the probability that all three cards are spades if none of the first two cards is replaced?
Answer:
[tex]\frac{11}{850}[/tex]
Step-by-step explanation:
Let's see
The probability of the first card being a spade is 13/52 (as there's 13 spades in the deck.
The probability for the second card is 12/51 (because there's 12 spades left in 51 cards total).
The probability for the third is - you guessed it! - 11/50
so the total probability is:
[tex]\frac{13}{52} \cdot \frac{12}{51} \cdot \frac{11}{50} = \frac{1}{4} \cdot \frac{4}{17} \cdot \frac{11}{50} = \frac{1}{17} \cdot \frac{11}{50} = \frac{11}{850}[/tex]
A more generic solution:
Let's use the binomials to find the solution with combinations:
We need to pick 3 cards out of 13. This can be done in
[tex]\binom{13}{3} = \frac{13!}{3!\cdot10!}[/tex] ways.
And the total number of ways to pick 3 cards out of 52 is:
[tex]\binom{52}{3} = \frac{52!}{3!\cdot 49!}[/tex]
So the probability is:
[tex]\frac{ \binom{13}{3} }{ \binom{52}{3} } = \frac{ \frac{13!}{3!\cdot 10!} }{ \frac{52!}{3!\cdot 49!} } = \frac{ \frac{13!}{10!} }{ \frac{52!}{49!} } = \frac{13 \cdot 12 \cdot 11}{52 \cdot 51 \cdot 50}[/tex]
Which again brings us to the result computed before.

for 7 we only need Pythagoras's theorem, know it?
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]
out of curiosity.. does the above formula seem "impossible" ? or does it make sense?
[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]
[tex]c^{2}[/tex] = 144 + 256
[tex]c^{2}[/tex] = 400
c = [tex]\sqrt{400}[/tex]
c = 20
x= 20
for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it
Cos(60) = 18 / x
I'll show you the algebra we need to use to get this formula so that we can find x
A = B / x ( this is how it looks above )
x = B / A , now just put in the parts
x = 18 / Cos(60) now solve it w/ your calculator.. :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator :/
x = 36
there you go, :)
